摘要: Abstract This paper presents the study of open-top hat structure subjected to quasi-static loading. The finite element models have been carried out using nonlinear ABAQUS. is mainly used as an energy absorber or a B-pillar in side car. usually flexural (bending) In this study, was eliminate effect closure plate on performance, and establish changing dimensions face web sides performance. Despite sides, perimeter preserved. procedure divided into three phases. first phase includes length determine best terms absorption (EA) maximum peak force hence bending resistance that represents higher performance structure. second uses different angles between angle third top bottom arc sizes with values verify their crashworthiness results phases shown T2 design 94 has outstanding therefore selected be further enhanced phase. wide range optimise further. R1212 It 14.5% more absorption, 18.8% mean load when compared T2-94.
